Abstract (en)

A device assembly (10) for calibrating a single-use sensor (14) before, during or after a biopharmaceutical manufacturing process step comprises a single-use process equipment assembly for performing at least a part of the process step. The single-use process equipment assembly includes a flow line (12) through which a medium flows in a defined direction during the process step. The single-use process equipment assembly further includes an integrated single-use sensor (14) for measuring or detecting a physical or chemical property at a measurement location in the flow line (12). The device assembly (10) further comprises at least one calibration line (18) and at least one switching means (22) inserted into the flow line (12) upstream of the measurement location. The switching means (22) include a flow line inlet, a flow line outlet and a calibration line inlet connected to the calibration line (18). The switching means (22) are adapted to selectively switch between a first (main) flow path, in which the flow line inlet (26) and the flow line outlet (28) are opened while the calibration line inlet (30) is closed, and a second (calibration) flow path, in which the flow line inlet (26) is closed while the calibration line inlet (30) and the flow line outlet (28) are opened. The device assembly (10) comprises a dedicated reference means provided in the calibration line (18). The dedicated reference means includes a reference sensor (48) or a reference source or a reference standard solution (40) related to the physical or chemical property to be measured or detected by the single-use sensor (14). The calibration line (20) may also be provided downstream of the single-use sensor (14).
